The database includes 87Sr/86Sr and 143Nd/144Nd isotopic ratios measured on bulk rocks of lava and pyroclasts sampled at Etna during 2020-2022 INGV-OE monitoring activity.
The chemical treatment of the samples was carried out in the clean laboratory of the INGV-OV. Before chemical dissolution whole rock have been dissolved with high-purity HF–HNO3–HCl mixtures. Sr and Nd have been separated from the matrix through conventional ion-exchange chromatographic procedures, described in detail in Arienzo et al. (2013, 2014).
Isotopic ratios have been measured by thermal ionization mass spectrometry (TIMS), using a Triton Plus® (Thermo Scientific) solid-source multicollector mass spectrometer in static mode. The blank was negligible considering the average Sr content of the samples; no determinations for Nd blanks was performed. Measured 87Sr/86Sr and 143Nd/144Nd ratios have been normalized for within-run isotopic fractionation to 88Sr/86Sr =8.375209 and 146Nd/144Nd =0.7219 respectively, using an exponential law for correction. During collection of isotopic data, replicate analyses of NIST-SRM 987 and JNdi-1 international reference standards have been performed to check for external reproducibility. During the period of analysis, the mean measured value (Goldstein et al., 2003) of 87Sr/86Sr 265 Sr for NIST-SRM 987 was 0.710242±0.000013 (2σ, where σ is the standard deviation of the values; n=48); that of 143Nd/144Nd for JNdi-1 was 0.512105±0.000007 (2σ, n=20) at Osservatorio Vesuviano. Sr and Nd isotope ratios of the samples have been normalized to the recommended values of NIST-SRM 987 and JNdi-1 (87Sr/86Sr 269 =0.710248; 143Nd/144Nd =0.512107; Zhang and Hu, 2020), respectively.

The data represent the total intensity (F) of the Earth's magnetic field (or geomagnetic field) acquired continuously by the stations of the Etna permanent network from XX to YY. All the stations are located along a South-North profile that crosses the summit area of Etna and are equipped with Overhauser effect scalar magnetometers with a sensitivity of 0.01 nT. The network also includes a reference station located in Cesarò on the Nebrodi Mountains. The data are synchronized by a GPS and is acquired with a sampling rate of 5-10 seconds. Time series of geomagnetic data allow to observe and evaluate the anomalous variations of the magnetic field associated with the modifications of the stress field and of the thermodynamic state produced by magma rising in the more superficial layers of the volcano. The continuous data analysis therefore contributes to the evaluation of the spatio-temporal evolution of the dynamics in progress.

We combine values of column height HTP and mass eruption rate QM, radar derived, including the associated wind velocity (vW) for several eruptive events of Mt. Etna (Italy). Hence, we use a Monte Carlo Markov Chain approach to fit a parametric model relating HTP, QM and vW. The fitted model can then be used to quickly infer QM from observed HTP and vW. An outstanding feature is that HTP and QM are obtained from the same sensor reducing the overall uncertainty.
Time trend of the radar-based estimates of the mass eruption rate (QM) and top plume height (HTP) for 32 Etna eruptions and the vw data retrieved from the reanalysis data of the ECMWF for the same events. For each event you can find: Time (UTC), top plume height (km); QM (mass eruption rate (kg/s)). Finally, vw is the wind velocity (m/s).

The database consist of Bulk rock compositions (major and trace elements) of lava and pyroclasts sampled at Stromboli during the 2020 INGV-OE petrologic monitoring activity.
The preparation and analyses of the sample have been performed at INGV laboratories.
After archiving, the samples were reduced to powder, the LOI was determined and finally they were melted (Miraglia, 2012). The beads were analysed for X-ray fluorescence.
The bulk rock compositions have been analyzed at INGV-OE with the Rigaku Primus II XRF.
The accuracy of our measurements has been checked through replicate analyses of the international standard (Jarosewich et al., 1980). The precision, expressed as relative standard deviation, is less than 1% for SiO2, Al2O3, FeO, MgO and CaO and less than 3% for TiO2, MnO, Na2O, K2O and P2O5 (Miraglia, 2013), <5% for Ba, Ce, La, Nb, Nd, Rb, Sm, Sr, V, Y, Yb, Zn e Zr, e <10% for Cr, Ni e Th (Miraglia, 2017). Each measure is the average of 3 analyses.

We computed new 268 focal mechanisms (1.3≤M≤4.6), with rays traced through the 3D velocity model of Scarfì et al. 2018, of events occurred in the southern Tyrrhenian Sea and northern Sicily between 1 January 2000 and 31 August 2021. The earthquakes were recorded by the land seismic network managed by the INGV and a seafloor network, consisting of 14 Ocean Bottom Seismometers and Hydrophones, deployed during the Tyrrhenian Deep sea Experiment (TYDE, December 2000 – May 2001; Dahm et al., 2002; Sgroi et al., 2006) and the NEMO-SN1 seafloor observatory (October 2002 – February 2003; June 2012 - June 2013; Sgroi et al. 2021).
We collected basic data (travel times and first polarities) from available datasets (ISIDe Working Group, 2007) and published studies (Sgroi et al., 2006; Barberi et al., 2006; Monna et al., 2013). Then we processed them using the 3D velocity model of Scarfì et al. (2018) and the tomoDDPS algorithm (Zhang et al., 2009). This software has the advantage of using a combination of both absolute and differential arrival times, so that for earthquakes with closely spaced foci, travel times errors due to inaccurate velocity models in the volume outside the cluster will essentially be cancelled. By using FPFIT software (Reasenberg and Oppenheimer, 1985), we obtained 268 focal solutions with an average uncertainty on the orientation of the nodal planes of about 10°. These focal mechanisms can be considered representative of the kinematics characterising the southern Tyrrhenian Sea and the northern Sicily, since they are distributed in all the main seismogenically active areas of the region.
The table (STyrr_FM_2000-2021) shows focal parameters of the analysed earthquakes. Specifically: ID = identification number; Date (year/month/day); O.T. = Origin Time (hour, minute, second and cent); Lat = latitude north in degrees; Long = longitude east in degrees; Depth in km; MagType = duration (Md), local (ML) or moment magnitude (Mw); Magnitude; Npol = number of polarities; Plane 1 (STRK, DIP, RAKE), Plane 2 (STRK, DIP, RAKE) = strike, dip and rake of the first and second nodal planes; P-Axis (AZM, PLNG), T-Axis (AZM, PLNG) = azimuth and plunge of the P- and T-axes; Q = quality of the focal mechanism (2 = best quality; 1 = medium quality; 0 = low quality); Cat = category of the focal mechanism (NF = normal fault, NS = normal-strike, SS = strike-slip, TF = thrust fault, TS = thrust-strike, HV = horizontal-vertical).
